Floating drug delivery systems are low-density systems that float over the gastric content and remain buoyant in the stomach for a prolonged period of time. They enhance drug bioavailability, declines drug wastage and provide controlled drug delivery and better patient compliance. Several approaches and techniques were developed in recent year for FDDS.
